Solve (-7x^4) (0x-5) (8x^21)

Question

Simplify the expression

280 x^{6}

Evaluate

(- 7 x^{4}) (0 \times x - 5) (8 x^{2} \times 1)

Remove the parentheses

- 7 x^{4} (0 \times x - 5) \times 8 x^{2} \times 1

Any expression multiplied by 0 equals 0

- 7 x^{4} (0 - 5) \times 8 x^{2} \times 1

Removing 0 doesn't change the value,so remove it from the expression

- 7 x^{4} (- 5) \times 8 x^{2} \times 1

Rewrite the expression

- 7 x^{4} (- 5) \times 8 x^{2}

Rewrite the expression

7 x^{4} \times 5 \times 8 x^{2}

x = 0

Evaluate

(- 7 x^{4}) (0 \times x - 5) (8 x^{2} \times 1)

To find the roots of the expression,set the expression equal to 0

(- 7 x^{4}) (0 \times x - 5) (8 x^{2} \times 1) = 0

Remove the parentheses

- 7 x^{4} (0 \times x - 5) (8 x^{2} \times 1) = 0

Any expression multiplied by 0 equals 0

- 7 x^{4} (0 - 5) (8 x^{2} \times 1) = 0

Removing 0 doesn't change the value,so remove it from the expression

- 7 x^{4} (- 5) (8 x^{2} \times 1) = 0

Multiply the terms

- 7 x^{4} (- 5) \times 8 x^{2} = 0
