Q. Use the quadratic formula to solve. Express your answer in simplest form.16p2+2p−15=−6pAnswer: p=
Identify coefficients: Now that we have the equation in standard form, we can identify the coefficients a, b, and c to use in the quadratic formula.a=16, b=8, c=−15
Use quadratic formula: The quadratic formula is given by (−b±b2−4ac)/(2a). Let's substitute the values of a, b, and c into the formula.(−8±82−4⋅16⋅(−15))/(2⋅16)
Simplify discriminant: Now, let's simplify the expression under the square root (the discriminant).82=644⋅16⋅(−15)=−960So, the discriminant is 64−(−960)=64+960=1024(−8±1024)/(2⋅16)
Take square root: Next, we take the square root of the discriminant. 1024=32 So, we have (−8±32)/(2⋅16)
Perform addition and subtraction: Now, we simplify the expression by performing the addition and subtraction.(−8+32)/(2×16) and (−8−32)/(2×16)(24/32) and (−40/32)
Simplify fractions: Finally, we simplify the fractions by dividing both numerator and denominator by their greatest common divisor. 3224=4332−40=4−5
