Hello! I need help converting these equations into factored form.
58. Convert each equation to factored form.
a) y = 4x – 20 y = 4x - 20 = 4*(x - 5)
b) y = x^2 - x – 12 y = (x-4)*(x+3)
c) y = 25x^2 – 36 y = (5x-6)*(5x+6) <<<---=== use the formula a*2 - b^2 = (a+b)*(a-b)
d) y = -9x^2 + 72x + 81 y = -9*(x^2 - 8x - 9) = -9*(x-9)*(x+1).
