If a quadratic function is represented as f(x) = (x - 7)(x + 8), find the zeroes.

• x = - 7 and x = 8

• x = 7 and x = -8

• x=7 and x=8

• x=-7 and x=-8

 $f\left(x\right)=\left(2x-3\right)\left(x-7\right)\left(x+1\right)$  check all the zeros of this function

•  $\frac{3}{2}$  

• -1

• 7

• -7

• 1

• -2, 4
• -8
• ±8
• No real solution
