Question

(A) We have the expression $9x^{2}-12x+4$.This can be written in the form $a^{2}-2ab+b^{2}$ where $a=3x$ and $b=2$.$9x^{2}-12x+4 = (3x)^{2} - 2(3x)(2)

Vedclass · Accepted Answer

$(3x-2)(3x-2)$

Vedclass · Answer

(A) We have the expression $9x^{2}-12x+4$.This can be written in the form $a^{2}-2ab+b^{2}$ where $a=3x$ and $b=2$.$9x^{2}-12x+4 = (3x)^{2} - 2(3x)(2) + (2)^{2}$.Using the algebraic identity $a^{2}-2ab+b^{2} = (a-b)^{2}$,we get:$(3x-2)^{2} = (3x-2)(3x-2)$.
