Answer:

$x^2 +2x-3$

Step-by-step explanation:

Given

$(x - 2)\² + 6x - 7$

Required

The equivalent

We have:

$(x - 2)\² + 6x - 7$

Expand

$(x - 2)\² + 6x - 7 = x^2 -2x-2x +4 +6x - 7$

Collect like terms

$(x - 2)\² + 6x - 7 = x^2 -2x-2x+6x +4 - 7$

$(x - 2)\² + 6x - 7 = x^2 +2x-3$

Hence, the equivalent is:

$x^2 +2x-3$

Answer:

$-\frac{15}{16}$

Step-by-step explanation:

$\frac{1}{4} ^{2}$ = $\frac{1}{16}$

2*(pq)= 2( $\frac{1}{6}$ )= $\frac{1}{3}$

-3 $q^{2}$ = -3 $(\frac{4}{9} )$ = $-\frac{4}{3}$

$\frac{1}{16} +\frac{1}{3}-\frac{4}{3}$ =

$\frac{1}{16} -1$ =

$-\frac{15}{16}$
