Question

I NEED HELP What is the value of x if x * x + 2x - 35 = 0?

Answer 1

Answer:

(x−7)(x+5)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x−7=0x+5=0

Set the first factor equal to 0 and solve.

x=7

Set the next factor equal to 0 and solve.

x=−5

The final solution is all the values that make (x−7(x+5)=0 true. x={7,−5}
