simplify sqrt(-24)*sqrt(-42)

simplify

- 24 \cdot - 42

- 127

Decimal Notation

- 31.74901 \dots

Solution steps

- 24 - 42

- 24 = 2 - 6

= 2 - 6 - 42

- 6 = 6 i

= 26 i - 42

- 42 = 42 i

= 26 i 42 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 26 i^{2} 42

= 2642 i^{2}

42 = 67

= 2667 i^{2}

Apply radical rule:

a a = a, a \geq 0

66 = 6

= 2 \cdot 67 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 2 \cdot 67 (- 1)

Multiply the numbers:

2 \cdot 6 (- 1) = - 12

= - 127

6 (2 + t) - 3 (t + 1)

(x^{2} + 3 x - 1) (x + 1)

(x - 7) (x + 10)

- x^{2} + 4 x^{2}
