Question

factories the following quadratic polynomials using middle term splitting i) x(power2) +12x +27​

Answer 1

Step-by-step explanation:

f(x) = x3 -2a x2 -5x +6a

if (x+2) is a factor, then f(-2) = 0

f(-2) = -8 -2a (-2)2 -5(-2) + 6a = 2 - 2a = 0

hence a = 1

Answer 2

Step-by-step explanation:

x(power2)+12x+27

X2+9x+3x+27

x(x+9)+3(x+9)

(x+3) (x+9)
