(5x+3)(2x-7)=0?

Question

Solve
(5x+3)(2x-7)=0
does this equal -3/5, 3????

im lost. need some help..thanks

Answer 1

To solve this problem you must combine like terms and multiply
1. (5x+3)(2x-7)=0
10x -21=0
Then add 21 to both sides
10x -21+21=0+21
You should get 10x=21
Divide 10x to both sides
10x/10=21/10
The answer should be 2.1
Plug in the x value to determine if it's correct

or split the equations
5x+3=0....2x-7=0
x=.06........x=3.5

Answer 2

The product is 0 when either term is 0.

So, either:

(a) 5x + 3 = 0
5x = -3
x = -3/5

or else

(b) 2x - 7 = 0
2x = 7
x = 7/2

I get -3/5 or 7/2, not -3/5 or 3.

Answer 3

a million. For it to be function, you are able to in trouble-free terms have one y fee for each x. So if there are 2 distinctive values for an identical x, then that is not a function. 2. anyplace you notice an x in f(x), plug interior the entire g(x) equation. 3. Set 2x-a million equivalent to 5 and -5 and clean up for x 4.Use formulation y=mx+b m is slope and you're given x and y. Plug them in and clean up for b. Then positioned it rewrite y=mx=b with the slope you're given and the b you come across. 5. I ought to allow you be conscious of confident. 6. stretch or decrease 7. the three stretches or shrinks it you come to a type I dont bear in mind and the - 2 strikes it down 8 and 9. element 10. use Descartes rule look it up 11. quadratic formulation 12. element 13. I dont be conscious of 14. quadratic 15 sixteen I dont be conscious of.

Answer 4

Using the zero-product property (if a product equals zero, then one of its factors must be zero), set each binomial factor equal to zero and solve for x.

5x + 3 = 0
5x = -3
x = -3/5 or -0.6

Also
2x - 7 = 0
2x = 7
x = 7/2 = 3.5

Answer 5

there are two ways u can answer this question. using the quadratic formula or the zero product rule.
x = 7/2, -3/5

Answer 6

(5x+3)(2x-7)=0
10x^2-35x+6x-21=0
10x^2-29x-21=0
(2x-7)(5x+3)=0
2x-7=0
x=7/2
5x+3=0
5x=-3
x=-3/5
What I got is x=-3/5 or 7/2.
