Question

$$30 { x }^{ 2 } -42 { x }^{ 2 } - { 35 }^{ 2 } +49x+5x-7$$

Evaluate

$-12x^{2}+54x-1232$

Solution Steps

Combine $30x^{2}$ and $-42x^{2}$ to get $-12x^{2}$.

$$-12x^{2}-35^{2}+49x+5x-7$$

Calculate $35$ to the power of $2$ and get $1225$.

$$-12x^{2}-1225+49x+5x-7$$

Combine $49x$ and $5x$ to get $54x$.

$$-12x^{2}-1225+54x-7$$

Subtract $7$ from $-1225$ to get $-1232$.

$$-12x^{2}-1232+54x$$

Factor

$2\left(-6x^{2}+27x-616\right)$
