Question

Simplify the following expressions:
(a) (x-1) (x-2) (x - 9x +44)
(x-7)(x²-3x+2)
(6) G² - 8x+12) G²-16)
(x²-36) (x²-4)​

Answer 1

x2 + 9x + 18  = x2 + 6x + 3x + 18  = x(x + 6) + 3(x + 6)  = (x + 6) (x + 3) ii. x2 – 10x + 9  = x2 – 9x – x + 9  = x(x – 9) – 1(x – 9) = (x – 9)(x – 1) iii. y2 + 24y + 144  = y2 + 12y + 12y + 144  = y(y + 12) + 12(y + 12) = (y + 12)(y + 12) Read more on Sarthaks.com - https://www.sarthaks.com/854182/factorize-i-x-2-9x-18-ii-x-2-10x-9-iii-y-2-24y-144-iv-5y-2-5y-10-v-p-2-2p-35-vi-p2-7p-44
