Question

factorise 64x raised to the power 2 + 16x + 1​

Answer 1

Answer:

Rewrite 1 as 12 . Check the middle term by multiplying 2ab 2 a b and compare this result with the middle term in the original expression. Simplify. Factor using the perfect square trinomial rule a2+2ab+b2=(a+b)2 a 2 + 2 a b + b 2 = ( a + b ) 2 , where a=8x a = 8 x and b=1 .
