Question

$$(5x+3)(9x-7)20$$

Evaluate

$900x^{2}-160x-420$

Solution Steps

Apply the distributive property by multiplying each term of $5x+3$ by each term of $9x-7$.

$$\left(45x^{2}-35x+27x-21\right)\times 20$$

Combine $-35x$ and $27x$ to get $-8x$.

$$\left(45x^{2}-8x-21\right)\times 20$$

Use the distributive property to multiply $45x^{2}-8x-21$ by $20$.

$$900x^{2}-160x-420$$
