Question

x square - 7 x minus 30

Answer 1

${x}^{2} - 7 x - 30 \\ \\ = > {x}^{2} - 10x + 3x - 30 \\ \\ = > x(x - 10) + 3(x - 10) \\ \\ = > (x - 10)(x + 3)$

Answer 2

Hey mate!.... Here is your answer.

x² - 7x - 30 = 0

=> x² - 10x + 3x - 30 = 0

=> x(x - 10) + 3 (x - 10) = 0

=>(x - 10) (x + 3) = 0

=> x - 10 = 0 OR x + 3 = 0

=> x = 10 OR x = - 3
