Answer:
[tex]7 {x}^{2} + 28x - 35 = 0[/tex]
[tex]7 {x}^{2} + 35x - 7x - 35 = 0[/tex]
[tex]7x(x + 5) - 7(x + 5) = 0[/tex]
[tex](x + 5)(7x - 7) = 0[/tex]
[tex](x + 5)(x - 1) = 0[/tex]
7 (x-1)(x+5)
Step-by-step explanation:
Find
GCF = 7
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
7 (7x^2/7 + 28x/7 - 35/7)
Simplify each term in parentheses.
7 (x^2 +4x-5)
Simplify.
